We're dividing 37943021 by 477 
We're looking to find how many times 477 goes into 37943021.

On to step 1:
3 divided by 477 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 477

On to step 2:
477 can be fit into 37 0 times, resulting in a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Grab the next digit (9) from the dividend, add it to 37, then carry on: 379 / 477

Let's proceed to step 3:
The number 477 fits into 379 0 times, leaving a remainder of 379.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 379 and we're left with 379.
Fetch the next digit (4) from the dividend, attach it to 379 and continue: 3794 / 477

On to step 4:
477 can be fit into 3794 7 times, resulting in a remainder of 455.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 3339 from 3794, we get 455.
Include the next digit (3) from the dividend after 455, then repeat: 4553 / 477

Advancing to step 5:
If we divide 4553 by 477, we get 9 and a remainder of 260.
The next digit of our result is 9. 
Result so far: 79.0
If we take 4293 away from 4553, we end up with 260.
Include the next digit (0) from the dividend after 260, then repeat: 2600 / 477

On to step 6:
477 goes into 2600 5 times with a remainder of 215.
The next digit of our result is 5. 
Result so far: 795.0
Subtracting 2385 from 2600 leaves us with 215.
Bring next digit (2) of the dividend behind the 215 and repeat the process: 2152 / 477

Step 7:
The number 477 fits into 2152 4 times, leaving a remainder of 244.
The next digit of our result is 4. 
Result so far: 7954.0
If we subtract 1908 from 2152, we get 244.
Include the next digit (1) from the dividend after 244, then repeat: 2441 / 477

On to step 8:
477 goes into 2441 5 times with a remainder of 56.
Put 5 as the next digit of the answer. 
Result so far: 79545.0
If we subtract 2385 from 2441, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
477 can be fit into 560 1 times, resulting in a remainder of 83.
The next digit of our result is 1. 
Result so far: 79545.1
Subtracting 477 from 560 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 10:
830 divided by 477 is 1 with a remainder of 353.
The number 1 becomes the next digit in our result. 
Result so far: 79545.11
If we subtract 477 from 830, we get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

After the division, we end up with 79545.11 and a remainder of 0.353.
